newRX-7

ok so here is the thing i bought an RX7 from a guy and he told methat there were no leaks but i soon found out that there was a leek coming from the resavour and so i went to take the brake lines off of the thing and for some reason he tightened them down so hard there is no way for me to get them off. any suggestions on a detergent or something i could put on the nut to loosen it up to come free/?

Be sure that you use a flare nut wrench, not a regular open-end wrench. The flare wrench grips better, and won't slip off when you apply the necessary force. You should not need to apply any lube to the threads to get them out. Also, where is it leaking? It could just be the seals that connect the reservoir to the cylinder itself. If that's the cause, you don't need to remove the cylinder. The reservoir just pulls off. And obviously, drain it before/if you do this.

ha thank you i just pulled the damn thing off but now i will clean it up in there and pull it off. that is what i thought but i wasnt sure thank you. uh a nother thing would brake fluid make the paint bubble up and peal away?

Yes! Brake fluid will attack the car's paint, so make sure you clean up the fluid already on the car and try not to spill more. Same thing happened to my car, and its been sitting with a leaky master cyl. for over a year and all the paint under the cyl. is flaking.

yes. brake fluid eats paint for lunch. take care of that or it will start rusting away. the bare body metal rusts quite nicely.
